I think about the character in the illustration process. It'll be more understandable in the concept(about to her superpowers). Morrigan is the goddess of war in Irish mythology (I like to be inspired by myths.) The goddess herself did not take part in the battles, but she certainly attended the battlefield and used all her power to help one side or the other.
In the illustration, a girl riding her horse. here she is not at war, she will have the next fight, and she should choose the right side. honestly, I don’t know how to show morale. -_-, maybe if I will have time, I'll think about this moment.
